Terminology Tuesday: Modalism
Modalism: Also called Sabellianism, the trinitarian heresy that does not view the Father, Son, and Spirit as three particular “persons in relation” but merely as three modes or manifestations of the one divine person of God. Thus God comes in salvation history as Father to create and give the law, as Son to redeem and as Spirit to impart grace.1
